Application filed November The present invention relates to a floor surfacing machine and an important object of the invention is to provide a machine of this class which will be simple, durable,

eflicient and which may be easily used for planing, sandpapering, rubbing or polishing the surface of the floor.

Another very important object of the invention resides in the provision of a machine of this nature which has its parts arranged in a compact and convenient manner and so as to permit the machine to operate effectively close to the walland intight place.

, With the above andnumerous other 0bjects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of'parts as will be hereinafter more fully described.

and claimed.

In the drawings: r I

Figure l is a side elevation of the machine embodying the features of our invention,

Figure 2 is another side elevation thereof opposite to that shown in Figure 1,

Figure 3 is a top plan view thereof,

Figure 4 is a vertical longitudinal section therethrough,

Figure 5 is a vertical section through the rotary planer, V

Figure 6 is an elevation thereof,

Figure 7 is a perspective view of one of the blades,

Figure 8 is a sectional elevation of the standing rotor, and

Figure 9 is an end elevation thereof. I Referring to the drawings .in detail it will be seen that the numerals 5 denote a pair of side walls which have a cover plate 6 bolted or otherwise secured thereto. An end Wall 7 is bolted or otherwise secured between the rear edges of the side wall .5. The side walls 5 are formed withhead extensions 8 having a curved plate 9 fixed therebetween by screws or the like. This head plate 9 is sectional having the bottom section 9 removable for permitting access to the space within the head part. These said extensions are provided with notches or openings 10 leading upwardly from their lower edges.

5; 1939. Serial in. 493,650;

Bearingplatesf llare adjustably mounted on the extensions to extend across the notches or openings 10 so that rotorsniay be ournalled therebetween either in the form of a rotary scraper, a rotary stamping device, a rotary polishing device or brush or other devices.

A suction fan 12 is 'mounted'between the side plates 5 and has its tangential outlet 4, 14 extending rearwardly through an open- "so ing in the upper portion of the plate 7 so that a dust bag or the like may be attached thereto. An inlet. conduit 15 is engaged with the center of'the fan and leads from y the head. A 1

'On the side walls there are formed bearings 16 to receive shanks 17-of forks'18 in which are journalled wheels 19. A bearing 20 is mounted on the rear end wall 7*toreceive the shank of a fork 21 -which is curved and has journalled between its extremities-shaft wheel 22. A threaded menu ber 25 is disposed through a lug-26 so asto adjust the height of the rear end of the machine.

The numeral 26 denotes a cylindrical member having tangential recesses 27 open 'ing outwardly adjacent semi cylindrical recesses 28. Blades 29 are adjustably mounted in the recesses 27 being held in place by "so screws 30. This cylindrical body 26 is provided with trunnions 31 and 32. The trun nion is journalled through its bearing plate l1 and has a sprocket 34 on the end thereof.

An electric motor 35 is mounted on the 8 5 cover plate 6 and has a sprocket 36 on its armature shaft. A- chain 37 is trained over the sprockets 34 and 36. In Figures 8 and c 9 I have showna sanding device comprising i a drum 40 with end plates 41 thereon and '90 trunnions 31 and 32. A recess is longitudinally disposed in the periphery of the drum d0 as-is indicated at 42 so that the sandpaper may be disposed about the drum {65 and anchored in place by the use of a key or the like in. the recess 42. This sanding device, of course may besubstituted for the scraping mechanism previously explained.

A brush or polisher may also be substituted. for either the sanding device or the scraping device. I

The fan is operated from the motor by means of a belt and pulley mechanism denoted by the numeral 45. v

g It is thought that the construction, operation, utility and advantages of this invention Will now be quite apparent to those skilled in this art without a more detailed description thereof. I The present embodiment of the invention has been described in considerable detail merely for the purposes of eXemplificati'on since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention'and the above description;

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to withoutdeparting from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages. Having thus described our invention,

what we claim as new is:

In a floor surfacing machine of the class described, a housing having an open bottom, front and rear wheels for supportingthe same, the housing having a forwardly, ex-

tending head part having openings in its side parts opening through the lower end of said side parts, a cross piece ex ended across each opening, means whereby each cross piece can be adjusted vertically, a tool member, trunnions thereon journalled in the cross pieces, a, removable part atrthe front vof the forwardly extended portion for providing access to the interior thereof, a fan device located in the housing having its in- 9 let extending to a point in rear ofthe forwardly extended portion thereof and its outlet extending through the rear Wall of the housing and a motor on thehousing for operating the tool member and the rotor of 4 the fan, and means for adjusting the rear wheel of the housing Vertically to tilt the housing on the front wheel to properly position the tool member with respect to the surface on which the device is movable.

In testimony whereof we alii-Xv our signatures. 7 e
